USNO-B cleaning, bugs

Jon Barron (UofT, Novartis) is in town and we worked on refining and writing up our work on cleaning the USNO-B1.0 catalog of spurious sourced caused by diffraction spikes and reflection halos in the plate imaging. We have a very conservative system with very few free parameters.

I also fixed some bugs I had introduced into the very fast and reliable pipeline that takes an image (any image) and returns the x,y coordinates of all the stars.
